Here's your fix, if you dont need it anymore then may it benefit some other poor soul.
You can fix this problem by blocking Word from using DDE to open files.
In the HKEY_CLASSES_ROOT\Word.Document.12\shell\Open key:
Delete or rename the ddeexec sub-key
In the HKEY_CLASSES_ROOT\Word.Document.12\shell\Open\command key:
Delete or rename the command value (not to be confused with the command key.)
Edit the (Default) value and add "%1" (including quotes) at the end
This solves the problem for .docx files. If you also want to solve it for .doc files, do the same thing for Word.Document.8
